When would overflowClipRect(...) be smaller than
style()->getRoundedInnerBorderFor(...) below? Related to my other comment.

+            return false;
         if (style()->hasBorderRadius()) {
             LayoutRect borderRect = borderBoxRect();
             borderRect.moveBy(accumulatedOffset);
             if (!locationInContainer.intersects(style()->getRoundedInnerBorderFor(borderRect)))
                 return false;
